The OLED display technology has the advantages of self-luminescence, wide viewing angle, almost infinite contrast, low power consumption, extremely high reaction speed and the like. In the OLED process development, the glass substrate is usually cut into four or six parts before entering the cell evaporation, and after cutting, the edge of the substrate and the shaping chamfer of the substrate need to be ground by using a formed diamond grinding wheel to remove stress and avoid cracking.

In the new process development stage, it may be evaluated that different generation line production devices are introduced, for example, the evaporation device is G3.5 generation line, and the inkjet printing device is G2.5 generation line.
